For example [brokers] ansible-slave node\_id=1 kafka\_port=9092 ansible-slave node\_id=2 kafka\_port=9093 ansible-slave node\_id=3 kafka\_port=9094 I started playbook but it is running only once not three times. How to achieve this thing using ansible? ---

The name must be uniqe, if the appear more than once only the last one count. To archive this you can do this. [brokers] ansible-slave node\_id=1 kafka\_port=9092 ansible-slave-v1 node\_id=2 kafka\_port=9093 ansible\_host=ansible-slave ansible-slave-v2 node\_id=3 kafka\_port=9094 ansible\_host=ansible-slave But remember, if you are using inventory\_hostname it will be the name in the inventory and not ansible-slave for the two last ones. ---

Thank you so much Kai for your solution. it will definitely help me. I am using inventory\_hostname so name will be different according to your solution but i wanted same name. I want to automate multiple kafka brokers on single node. that’s why i am looking for the solution. As in server.properties file name will be different so it won’t work. i tried below thing [brokers] ansible-slave node\_id=1 kafka\_port=[9092,9093,9094] ansible-slave-1 node\_id=2 kafka\_port=[9092,9093,9094] But i am not able to iterate through kafka\_port list with **with\_items** looping construct. One more thing i need to do i.e. broker.id where i need to start from value 1 and end to a number which is total number of brokers. How can i achive this? Is there any notion of global variable which i can update and use further. For example in above case you can see i want to have three brokers on ansible-slave node on ports 9092,9093,9094 and three brokers on ansible-slave-1 node port 9092,9093,9094 so total brokers count 6 so i want to assign broker.id 1 to 3 in the ansible-slave host and 4 to 6 in ansible-slave-1 host. Thanks in advance Shubham Jain ---

I don't think you can specify a list in the inventory, you would need to use host\_vars/ folder for that. Or you can do this "kafka\_port=9092,9093,9094" and the with\_items will be with\_items: "{{ kafka\_port.split(',') }}" > One more thing i need to do i.e. broker.id where i need to start from value > 1 and end to a number which is total number of brokers.

When you are using the with\_items above or something simular you could calculate it, the item is the kafka\_port {{ item - 9091 + (node\_id - 1) \* 3 }} ---

**Thank you so much kai. your solution made my day and it is totally great and worked out finally.** One more Question - Can we use dictionary in inventory hosts section like below and access it in task using **with\_dict** and **item.key** and **item.value** as i have tried this but didn’t get success [brokers] ansible-slave node\_id=1 kafka\_dict={1:9092,2:9093,3:9094} ansible-slave-1 node\_id=2 kafka\_dict={1:9092,2:9093,3:9094,4:9095} Then i declared them in variables section then i got success [brokers] ansible-slave ansible-slave-1 [brokers:vars] kafka\_dict={1:9092,2:9093,3:9094} I was able to use then item.key and item.value with with\_dict construct and everything worked fine but now i need to add different dictionary of ansible-slave-1 host how can i add that since this dictionary is common? I tried adding one more kafka\_dict with different values in brokers:vars but one of the kafka\_dict is used in playbook for both of hosts i.e. last one. for example like below [brokers] ansible-slave ansible-slave-1 [brokers:vars] kafka\_dict={1:9092,2:9093,3:9094} kafka\_dict={1:9092,2:9093,3:9094,4:9094} Can we define a host specific variables?

In the inventory it's specified on the same line as the host. But you can use host\_vars/ansible-slave.yml file instead. ---
